4.8

(6 reviews)

Read speeds up to 100 MB/s enable quick file transfers on USB 3.2 ports.

✓Large 256 GB capacity is sufficient for storing 4K video files, photos, and backups.

✓Plug‑and‑play compatibility across Windows, macOS, and Linux without needing additional drivers.

Cons

✗Manufacturer does not specify write speed, and similar models report write performance as low as ~10 MB/s.
✗Plastic construction may feel less premium and could be less durable than metal‑cased competitors.
✗Real‑world transfer speeds drop noticeably when the drive is used on USB 2.0 ports or older systems.
✗Physical dimensions (58 × 20 × 13 mm) are bulkier than ultra‑slim alternatives, reducing keychain comfort.
✗Swivel mechanism adds a small moving part that could wear over long‑term heavy use.

From Expert Reviews

Praised by Experts

✓Convenient capless swivel design eliminates the risk of losing a protective cap.
✓Stylish black plastic body offers a simple, understated appearance suitable for professional environments.
✓Read speed of up to 100 MB/s is adequate for everyday file transfers on modern USB 3.2 devices.

Criticized by Experts

✗Plastic build is perceived as less premium compared with metal‑cased USB drives.
✗Write performance is not disclosed, raising concerns for tasks that require fast writes.
✗Performance degrades on USB 2.0 ports, limiting usefulness on older computers.

From User Reviews

Users Love

✓Compact size and lightweight feel make it ideal for attaching to a keyring and carrying daily.
✓Capless swivel mechanism is praised for preventing lost caps and protecting the connector.
✓Plug‑and‑play operation is appreciated for its ease of use across multiple operating systems.

Expert Opinion

Editors and product listings highlight the UC310’s convenient capless swivel design, straightforward plug‑and‑play operation, and respectable 100 MB/s read speed, positioning it as a reliable everyday storage solution. However, they note the lack of disclosed write speeds, a plastic chassis that feels less premium, and reduced performance on older USB 2.0 ports.

What Users Say

Although direct user reviews are absent, the product’s description and retail listings suggest consumers value its portability, capless swivel protection, and ease of use, while expressing concerns about unknown write speeds and a less‑premium feel.

Common Complaints

Unspecified write speed leading to uncertainty about performance, plastic build perceived as cheap, noticeable speed drop on USB 2.0 ports, and bulkier dimensions compared with ultra‑slim competitors.

How It Compares

vs. SanDisk Ultra Fit 256GB

Advantages

✓Much smaller footprint (28 × 12 × 5 mm) for tighter keyring fit
✓Higher advertised read speeds up to 400 MB/s

Disadvantages

✗Fixed capless design offers no physical protection for the connector
✗No swivel mechanism, so connector is exposed when not in use

Choose SanDisk Ultra Fit if you need the smallest possible drive and faster reads; choose ADATA UC310 for swivel protection and a more robust form factor.

vs. Samsung FIT Plus 256GB

Advantages

✓Compact size (23 × 19 × 8 mm) and high read speeds up to 400 MB/s
✓Reputable brand with strong performance reputation

Disadvantages

✗Fixed capless design without protective swivel
✗Potentially higher price point

Samsung FIT Plus is better for users prioritizing speed and minimal size, while ADATA UC310 is preferable for those who want a protective swivel and a lower‑cost option.

vs. Kingston DataTraveler Exodia 256GB

Advantages

✓Similar read speed (100 MB/s) at a lower weight (~5 g)
✓Cap design may feel more solid to some users

Disadvantages

✗Uses a traditional cap that can be lost
✗Lacks the swivel protection of the ADATA model

Kingston is a good alternative if you prefer a lighter drive with a cap, but ADATA’s swivel mechanism offers better connector protection without a removable cap.
